## @deftypefn {Function File} @var{odsinterfaces} = getodsinterfaces (@var{odsinterfaces})
## Get supported OpenOffice.org .ods file read/write interfaces from
## the system.
## Each interface for which the corresponding field is set to empty
## will be checked. So by manipulating the fields of input argument
## @var{odsinterfaces} it is possible to specify which
## interface(s) should be checked.
##
## Currently implemented interfaces comprise:
## - Java & ODFtoolkit (www.apache.org)
## - Java & jOpenDocument (www.jopendocument.org)
## - Java & UNO bridge (OpenOffice.org)
##
## Examples:
##
## @example
## odsinterfaces = getodsinterfaces (odsinterfaces);
## @end example
